[Help] Grove bluetooth v.03


I recently bought that grove bluetooth v.03 and it was working very well with the example script available on seedstudio

But now I’m facing issue with the serial, the character received is always the same

I can read on the serial this character" ÿ " or something else wrong ( no matter what is really sent )

This thread was talking about the same issue issue http://forum.arduino.cc/index.php?topic=176755.0

Thank you

Dear Customer

Hello, thank you for your answer but I already know this.

My serial is configured at 9600 and same for the grove ( by default )


I’m still having troubles with this grove bluetooth.

Any idea is welcome, thank you !

Nobody know how to manage this issue ?

Dear Customer

I’m sorry, because we don’t have the corresponding Bluetooth module, we can’t test your problem yet, but we will solve your feedback problem in the next week.

Hello, thank you for the answer

I prefer that there is not confusion with the grove because I failed my title in this topic, I’m talking about this groove <LINK_TEXT text=“http://wiki.seeedstudio.com/Grove-Seria … ooth_v3.0/”>http://wiki.seeedstudio.com/Grove-Serial_Bluetooth_v3.0/</LINK_TEXT>
